Being in love with your straight sempai isn't easy, but being in love with your straight, homophobic, and (to top it off) tyrannical sempai can be hell! And that's something Tetsuhiro Morinaga can relate to... especially now that he's had a taste of the forbidden fruit!

Features the same homophobic brother from Challengers, but this time as the main character!

Contains an extra story called Bokutachi no Shippai in v.5 featuring Masaki and Morinaga's big brother Kunihiro.

Takanaga Hinako confirmed on her Twitter account that her manga Koisuru Boukun will resume serialization in the February's 2015 issue of Kaiohsha's Gush magazine.

I'll say it in a few words. If Yamane Ayano's serie Finder is such a beloved one and it's all about rape (without funny stuff or an actual plot) how can peolpe say things like this one is horrible? This manga is simple, funny, cute and sexy. Do Morinaga rapes Souichi? Well, if you're raping someone you don't prepare them and try them to feel good. But if you want to consider it as raping and Morinaga a serial rapist (WHAT THE BLOODY F*CK?), ok go ahead, but you'll have to admit that it was only one time. Blackmail? HECK NO. How can you blackmail ANYBODY with "I'll go away if you don't do it with me" If it were me I would just laughed at him and kicked him 'till dead...But well. YOU that you're interested in reading this beautiful manga, do it, it's great. I'm a comedy lover, I know what I say. If you're looking for some really realistic or melodramatic stuff this isn't for you, but if you're on the search of a good, funny, sexy and with-a-good-plot manga this is a MUST.

This was the most disgusting manga I've ever read. Rape is in no way something "fluffy" or "cute." If you thought this was good, then I suggest you really think about what you just read. Don't just read manga and let it pull you around by the nose. Think about what you're reading and question things.

You want some manga that is entertaining, consensual and has a better plot than the whole mess this manga is? Well, I suggest you try Honto Yajuu, Konbini-kun, Kimi Note or even Kanjou Spectrum (though it's just Shounen-Ai). Just.. do yourself a favor and read anything but this. Don't let the ratings fool you.

And to the commenter above me: really? You're REALLY saying rape is okay as long as it's once and the rapist considers not going dry into the poor guy? World of a difference that makes... Oh wait, it doesn't. The other person was still raped. And let me remind you, this is a manga, AKA a work of fiction, and the sheer fact that this mangaka thought it was pretty rational to have her characters be that stupid to be blackmailed by something like that is her genius at work. Manga ≠ real life and this mangaka tends to always go very far from realistic reactions. But the issue here is that of her making rape seem okay is what's wrong. You should never feel that way no matter if it's a work of fiction or real life events.

One of the most disappointing pieces not just for its content (yup, sorry rape apologists, but 'no means no' and even if a dozen volumes later the victim succumbs to his stockholm syndrome and thinks he's fallen for his rapist, HE WAS STILL RAPED) but for the fact that it's brought out so much disgusting responses in its defenders. Morinaga's up there with some of the worst characters in BL--because he's the type that's woobie and adorable and makes you want to cuddle him, lulling people into this false sense of security where you forget what a HORRIBLE friend he was, taking advantage of the person he loved when they were vulnerable and he KNEW they didn't want it--AND THEN EMOTIONALLY BLACKMAILING THE GUY INTO STAYING WITH HIM.

Legitimately one of the worst things to hit BL fandom in a long while. So fricking glad it's coming to an end.

While I find most Takanaga-senseis work quite dull this one was fun. It had story and characters had emotion and stuff (as I said I find her other works dull) Even if it starts off as "rape" I find the story quite ok. And to defend the poor dude Morinaga was drunk and Souichi was indeed at fault too. From that on it's typical Uke-in-denial story. It's not like he's raping him all the time, (if that was true then all uke-in-denial manga is rape). He didn't really have to sleep with him (the reason he did was a bit wtf though). And even if it took him friggin 7 volumes but it ended up well.

Comedy is quite good and art is great. Story is not really believable but it's ok with me, I liked it.

I really like this series, though I can appreciate it's not for everyone. A lot of people can't get past the premise, and would consider most (if not all) of the sex scenes in the manga rape. Since I don't think yaoi is supposed to be extremely realistic and serious, I didn't mind. In real life Morinaga and Tatsumi might be considered scary, unpleasant people, but this is fiction. If you want realistic, go read Sakura Gari. If you think a love story between a neurotic, abusive, homophobic closet case and an adorable serial rapist sounds like it could be interesting, this is the right manga for you.

As for the rest, the art is good to begin with, and it only gets better as it goes on. The pace is also good, it doesn't drag or get suddenly weird later on. The story sort of sucks you in and it doesn't feel repetitive despite the fact that character development is really slow. The ending did feel a little rushed to me, but satisfying nonetheless.

I wish there were more long, quality-consistent yaoi manga out there. This one gets an enthusiastic 10 from me.

The art is one of my favorites, but I found Tatsumi so incredibly annoying in the beginning due to his unrelenting stubbornness. I'm liking him more since the story started actually progressing (just finished volume 5). I found Morinaga to be very adorable; it's hard to believe his past relationships. I just can't help but like the excited-puppy-types. I just hope the last few volumes have more going for them besides the steamy scenes, otherwise I'll be thoroughly disappointed and feel like I wasted my time with such a slow series.

Well, I pretty much feel exactly like "streetwalker", this persons comment was exactly what i think so i won't repeat ^^ But honestly i do want to repeat that the stuff about blackmail and rape is so not true. It's only the very first time it can be considered rape, since at that time Souichi was too weak to resist, but the other times have nothing to with rape or blackmail. You cannot blackmail a person by saying that you will leave them if you don't get your will, seriously. And Souichi says a million times that if he was blackmailed by anyone else, he wouldn't let them do anything. And honestly Souichi is not a weakling or a girly guy, if he seriously didn't want to do it with morinaga, he would have kicked his ass and choked/stabbed him or something like that, but he didn't! So obviously it's not rape, neither is it blackmail, it's all just an excuse for him letting morinaga do that stuff with him without resisting, just like "streetwalker" said, it's not that he doesn't want it, it's that he doesn't want to want it and therefore, the excuse of him being "blackmailed" and "raped". And also whenever morinaga looks at him that special way Souichi always gets all flustered and blushes and all that. Not exactly how you would act if some bastard who had been raping you several times looked at you lovingly -__-

So seriously, i don't understand why some people are writing those sort of lies in these comments, it's like they haven't even read the manga!

So to those people that were thinking of reading it, READ IT and you'll understand that it's a totally great, cute and hilarious manga, that doesn't have the usual rape=love plot that so many yaoi mangas have! Honestly, it's really great in every way and every chapter is entertaining!

I don't get all the fuss about non-con regarding this manga. I'd say whoever seriously thinks the whole series is some rape fantasy hasn't really read it. The first time it happened was definitely rape but only the first time and even that wasn't planned or anything. It wasn't graphic, it wasn't cruel so as rape goes this was pretty tame.

When you look at the story more closely, all the pieces click. The "blackmail" is basically Morinaga saying he'll leave if Souichi can't give him what he wants from their relationship. Hardly criminal, right? If Morinaga really was sexually abusing him, wouldn't Souichi want him gone? The only reason it's even labelled as blackmail is because Souichi needs an excuse for giving in. And the way I see it, Souchi doesn't refuse the sex because he doesn't want it, but rather because he doesn't want to want it, and there's a big difference... He just doesn't want to be a homo and this manga makes great use of the whole denial trope. I was actually more shocked by Souichi's violent outbursts than Morinaga's sexual behavior.

As for the rest, well the characters are all wonderful. Morinaga is super sweet, sympathetic and easy to relate to. There's also great character development especially when it comes to Souichi and the couple growth is truly touching. For such a funny manga this is very deep. The art is great and the sex scenes are some of the most sensual you'll ever read...

Highly recommend! ♥ And if you decide to read it, don't merely skim through it or you might just miss the whole point...

I honestly seriously hate this serious, it really unrealistic and even for fiction its bad. What person or persons would fall in love with someone that blackmails them and rapes them all the time. Every chance morinaga got he wanted to rape souchii . Its like the dude was sick in the head. I say it unrealistic cause i have gay male friend. and even in his opinion its bad. No one male or female would ever fall for anyone that would rape them constantly. I dont see why people love this. Cause i believe if you love this ,then something wrong. The end of story didnt end well at all. Moringa left souchii , and they both stay in to different prefecture in japan. So i dont see them as lovers. I see them as friends with benefits. Except one enjoys it more, just cause a person comes,are get hard does not mean there enjoying it .. People get rape a lot times and either or i spoke about before happens. i just seriously hated this one. She a great artist,and the some comedy was cool. But sex parts,excuse me rape parts were seriously annoying . Oh wait i forgot in volume 4.1-4.7 where masaki rape ,morinaga brother while he was chain, I justed wanted to take my pc and throw it against the wall. Come on come on, i guess yall love that too. the dude was serious he wanted to get hell out, oh and then she wrote and made him fall in love with masaki . I just think the author was have serious lusty wants , or did some weed when she tranlated on paper.

Not much I can say that hasn't been said. There's some non-con issues so I can understand how it could give some people squick. But really compared to SO many other yaoi this is practically a romance, just with one person extremely, extremely uncomfortable with his sexuality. Though that's just one interpretation, it's the one I prefer. I have read various takes on Souichi's feelings and actions but ultimately people seem to agree this is a compelling manga that makes you think about the lines between love and friendship. I personally really enjoyed it because it was funny, had good characters, great artwork and great sex.
